Get your data using `$("#img1").src.split(",")[1];` and then send it using whatever mechanism in the links above — Satej S, Jan 23 '16 at 11:45
@SatejS — That gives *PHP Parse error: syntax error, unexpected '(', expecting variable (T_VARIABLE) or '$'* — Quentin, Jan 23 '16 at 11:46
Correct, my method suggests sending the value from HTML to PHP via JS.That is, using JS to extract the exact data item required, and then sending it via POST/anything etc. — Satej S, Jan 23 '16 at 11:48
@SatejS — So rather than just parse the HTML with PHP, they should grab all of the HTML, modify it to add JavaScript, send it to a browser, get the browser to extract the data, then send it back to the PHP (presumably by making an HTTP request and triggering a second PHP script) … this sounds like a massively overcomplicated approach to the problem. — Quentin, Jan 23 '16 at 11:50

Assign an id (test) to image element and with jquery you could fetch src attribute of image with below code.

Jquery

var srcImage = $("#test").attr("src");

Or with Javascript

var srcImage = document.getElementById("test").getAttribute("src");

Now you could perform string operation on srcImage if you want particular part of src

Sorry Jazz I did not notice that it was exclusively for php. Kindly refer to question tagged by Quentin as reference. It provides multiple options on how to load/parse html content in php.

There are multiple ways to parse html from string/file/url. Once parsing is performed you could fetch elements from parsed content with supported functions. After referring to answers in tagged question I found SimpleHTMLDOMParser easy to use.

You could you it as below for your problem in particular.

Load HTML from file/URL

$html = file_get_html('http://www.example.com/'); //Your HTML url or file

Find image with attribute id=test

$ret = $html->find('img[id=test]'); //this will work if image element has ID if you can not change html then use foreach method mentioned in documentations.

Get a attribute ( If the attribute is non-value attribute (eg. checked, selected...), it will returns true or false)

$value = $ret->src;

This is what I understood by referring to documentations here. I have not tested it. http://simplehtmldom.sourceforge.net/ and http://simplehtmldom.sourceforge.net/manual.htm#section_find

Give it a try and see how it works out. Also refer to other possibilities from tagged question and choose whichever is easy for you. I hope it helps you. lmk.

yes now it working , now if any one wants in php then convert it , don't do down votes , he try to help atleast — Amitesh Kumar, Jan 23 '16 at 11:45
@Jazz you are welcome. I updated answer with solution from my understanding of simplehtmlparser. Please try and check if it works for you. AmiteshKumar Thank you for consideration. I got to learn few things about php :) — pratikpawar, Jan 23 '16 at 12:33
